TYPOGRAPHICAL SLUG CASTING MACHINE Filed Sept. 1:5, 1934 2 Sheets-Sheet2 Patented June 2', 1936 TYPOGRAPHICA SLUG CASTING CHINE ChristianAugustus Albrecht, Berlin, Germany, assignor to Mergenthaler LinotypeCompany, Brooklyn, N. Y., a company of New York Application September15,v 1934, Serial No. 744,193

' l In Germany September 15, 1933 This invention relates' tovtypographical slug casting machines such as those known ycormner-,cially under the registered trade-mark Linotype, wherein thetypographical Vslugs cast from a composed line of matrices presented tothe face of the mold are ejected from the mold as Vthey are successivelycast into a receiving galley in which they are assembled side bysiderbymeans of a periodically operated stacking device.

It is customary in such machines to allow the slugs to cool in thegalley by exposureV to the atmosphere. In the case of large'slugs',however, owing to the considerable mass of metal contained therein, morerapid cooling isneoessary, and it has therefore been vproposed toprovide the galley itself with water cooling means by'which Water isprojected against each slug in the galley before the slug is advancedtherein to make room for the next slug cast. Thisproposedarrangement,however, does not actually comply with all the requirements, especiallyas the action of the cooling water cannot be conveniently conned to theindividual slug last delivered to the galley. According 4to the presentinvention'each slug is individually cooled after ejection 'from the moldand before'it is delivered to the galley. `,For'this purpose, accordingtothe invention, a'receptacle supplied with cooling water -is provided'closely adjacent to Vthe'entrance end ofthe galley, and each slug onejection is received within'th'e receptacle on a`s1ug lifter whichis'raised and lowered in timed relationship with .the operative cycle ofthe machine, so that after cooling Within the receptacle theslugis'raised to the levelof the galley and transferred therefrom to thestacking device. f' g The accompanying drawings illustrate oneconstructional form of the inventionk- Inr ther said drawingsz- Figure 1is a side elevation, partly in section, of the pertinent parts of amachine with the invention applied thereto;

Figure`2 is a sectional'plantaken onvthe line A--A' of Figure 3, and

Figure 3 is a front elevation.

Referring to the drawings, I indicates the mold wheel which, asordinarily, is rotatably mounted on a mold-wheel slide movable forwardlyvand backwardly in the machine framef.-`"In Figure l1,

v a mold is shown in the ejecting positiomwith a ribbed slug 2, ejectedtherefrom by the ejector blade 3, about to fall tothe slug galley`5. Thegalley itself is in the usual form of an inclined shelf with anupstanding flange vat its lower'end,

, on which the slugs are stacked sideby'side.

`corresponds with the internal width of the recepj 'Ihe receptacle 6 isprovided at the right hand end of the galley, as seen best in Figure 3,its opened top lying in the same plane as the galley shelf and belowandforwardly of the slug ejecting position of the mold. The receptacleis preferably Asupported on the vise frame of the machine and at theupper part of its rear wall it is fitted with a water supply pipe l. VAwater outlet pipe B connects with the bottom of the receptacle. The'customary chute 9 which receives the ejected slugs and guides themtowards the galley 5 has its lower end flush with the rear of thereceptacle 6, so that the slugs are guided into the said receptacle.Within the receptacle 6 is fitted a slug lifter 'comprising an inclinedshelf or oor I0 se- 15 cured to a yoke or frame II and guided forvertical movement Within the receptacle, for example by" guiding ribsI2. The inclination of the slug lifter shelf I0 is parallel with that ofthe galley 5 and the width of the shelf I0 practically 20 `tacle.' IA'slug, on leaving the chute 9, is there- 'fore received on the sluglifter shelf I0 within the receptacle in the position indicated by theslug 2 represented in-dot and dash lines in Figure 1.

At the upper vend of the yoke II is mounted a screw' or pin I3, whichengages a longitudinal slot I4 on a lever I5, I1. This lever rocks aboutapivot I6 on the vise frame, and its arm I1 is located in the path of apin I8 on a link i9, which is connected to a lever 20 serving to movethe, first elevator 2| up and down in the usual manner. When the firstelevator descends, the pin I8 engages the lever arm I1 and thus raisesthe 'slug lifter I0, Il from its lowermost position, in

which it is shown in fu11 lines in Figure 1, into its 35 uppermostposition indicated by dot and dash lines 'in the said figure, in whichlatter position the shelf I0 of the slug lifter is'at the same level asand flush with the galley 5, so that a slug lying "on the shelf I0 canbe readily transferred to ther slug galley. On top of the receptacle Bis mountr galley 5. K Ytened one end of a spring 26, whose other end ised a slug stacker 22, which is adapted to rock about a pivot 23 on aU-shaped bail 24. The bail 24 embraces the receptacle 6 and its innerarm is connected to a horizontal slide 25 beneath the To the said arm ofthe bail24 is fasanchored to a pin 2l on the machine frame. This spring26 tends to maintain the slide 25, bail 24 and slug stacker 22 in theposition in which those parts are shown in Figures 2 and 3, in which theoperative surface of the slug stacker 22 (the surface directed towardsthe left in Figure 3) is adjacent to the entrance of the galley. To theslide 55 25 is attached a link 28 (Figure 2) which is plvoted to one endof a bell-crank lever 29, mounted on a fixed pivot 35 on the machineframe, and the second arm of said lever carries a roller 3| adapted tobear against the mold wheel or the mold slide. When the mold slide movesforward, the lever 29, slide 25 and slug stacker 22 are moved outwardlyto the position in which they are shown in dotted lines in Figure 2, inwhich the operative surface of the slug stacker is flush with the outerwall of the receptacle 6.

The cooling water is supplied through a hose or pipe 32. This pipe maybe provided with a valve, not shown in the drawings, controlled by aperiodically operated organ of the machine s o that water will be turnedon only at definite intervals, when a freshly cast slug is ejected, andcut off after the cooling.

The mode of operation of the device is as follows. When the slug lifterI0, Il is in the position in which it is shown in full lines in Figure1, a slug 2, ejected by the ejector blade 3, slides down the chute 9 anddrops into the receptacle 6 on to the shelf l0 of the slug lifter.

If the supply of water is under control, it will be turned on at thatmoment and the water will be sprayed through the pipe I on to the slug 2supported within the receptacle. If the supply of water isuninterrupted, the slug Will simply fall through the jet of water andwill be sprayed continuously. The cooling water leaves the receptaclethrough the outlet pipe 8.

When the first elevator descends, the slug lifter l0, Il, actuated bythe lever 20 through the connections I9, Il, I5, will be raised into theposition in which it is shown in dot and dash lines in Figure 1, and theslug will thus be brought to the level of the slug galley 5. The slugstacker 22 on top of the receptacle 6 is turned upwardly about its pivot23 by the upward movement of the slug. Then follows the forward movementof the mold slide, which withdraws the slug stacker 22, through thelever 29, link 28 and slide 25, so that its operative surface will bebrought behind the slug and, on the subsequent return of the mold slide,the slug stacker will be moved under the action of the spring 26 intoits original position and move the slug which has been cooled, from theshelf ID into the galley 5. At the next cycle of the machine, theseoperations are repeated.

The constructional form of apparatus above described and illustrated inthe accompanying drawings constitute the convenient and preferred formof the invention, but it will be understood that changes andmodifications may be made in the construction and operation of the partswithout departing from the invention. For example, the raising andlowering of the slug lifter and the actuation of the slug stacker may becontrolled by special cams on the main cam .shaft of the machine,instead of from the first elevator or the mold slide.
